Hyphessobrycon erythrostigma
Bleeding Heart Tetra
Bleeding Heart Tetra, Hyphessobrycon erythrostigma is a peaceful mid-dwelling community fish in the aquarium. Grows to the size of 7cm and lives about 5 years. It requires warm water  26 degrees C. This fish, like most tetras, needs soft, acid water, pH 6.5-6.8, with plenty of plants. This fish is somewhat susceptible to velvet disease and Ich. This fish is sensitive to water conditions. Does not usually live more than five years. Requires frequent partial water changes.Bleeding Hearts are generally a peaceful fish but fin nipping may become a problem, Males can be territorial. Keep them in a small school (6 or more) and try not to keep them with fish with larger fins such as angelfish and bettas. They do well in a variety of community tanks, and like most tetras they do best in groups and with bushy plants. Make a great tank mate for corydoras and other bottom dwelling species. They are peaceful when they are surrounded by their own kind with a few exceptions, just like tiger barbs. They are also mischievous, nipping at others' tails and entering their territory looking for food.
